The Radion Pro looks "sterile" compared to the 32. I thought the Radion Pro would have beaten the RB light outright, but I completely prefer the RB light. Seriously, I expected so much more. It's a huge pain in the *** to play with settings too. I have to have my laptop connected via usb to make changes and know what is going on.

I'll have more shots and impressions later, with PAR readings by tomorrow night.

Basically, with the Radion hung 9.5 inches above water level, it hits ~950 dead center 2 inches below the water line. Keeps ~300 at the sand bed 21" down. I would need to use 4 units to keep the entire tank that way. PAR drops off steadily to the sides.

At 8 inches above the water line, the RB unit hits closer to ~1050, and maintains around ~380 at the sand bed dead center.

For half the price, you get the around the same PAR and more coverage.

Glad to finally see someone producing a realistic unit at a reasonable price. One thing I've had against LED in general is that you either end up with a cheap, inferior product, or pay a small fortune for a massively overpowered one with a lot of unnecessary whistles and bells.

Btw, what if you turn white down on radion? Wonder what that will do to color and par.

In the first picture, White is turned down to 75%. It's using the 14k setting on the Radion Pro in Ecosmart. In the 18k and 20k setting, white is turned down to 37-45% and is definitely more blue, but it maintains a similar overall look.

Coral and fish look great under both (which I believe pop from the violets and reds), but side by side its hard to justify the price premium, especially when the PAR numbers are similar.
